The Study on the Influential Factors of Photocatalytic Performance of Eosin-Sensitized TiO₂ Nanoparticles

Abstract:

The photocatalytic activity of eosin-sensitized TiO₂ nanoparticles on photocatalytic degradation rate (PDR) of methyl orange under sunlight irradiation was studied. The influential factors on the degradation, such as eosin concentration, TiO₂ dosage, sensitization time and sensitization temperature were also investigated. The results show that: The performance of TiO₂ nanoparticles for PDR of methyl orange has been improved obviously for eosin sensitizing. The PDR of methyl orange reached 45.28% under the conditions of eosin concentration of 20mg/L, TiO₂ dosage of 0.5000g/L, sensitization time of 24h and sensitization temperature of 20°C.
